C2: Noise reduction capacitor Capacitance : 0.1 to 0.22µF Rated voltage : 200V or higher Use a film or ceramic capacitor. Evaluate under actual operating conditions. Capacitance : 100 to 470µF Rated voltage : 25V or higher, ESR is 0.25Ω max. Ripple current is 0.4Arms or above. Evaluate under actual conditions. D1: Rectifier diode In the absolute maximum ratings, the reverse peak voltage should be 400V or higher, the average rectifying current should be 0.5A or higher, and the peak surge current should be 20A or higher. (Full-wave rectification can be used) L1: Choke coil Coil for switching regulator. The inductance should be 820µH, the rated direct current should be 0.42A or above in order to prevent excessive heat generation or oscillation. R1: Noise reduction resistor 10 to 22Ω 1/4W The ideal value can be determined through actual testing. ZNR: Varistor A varistor must be used to protect against lightning surges and static electricity. www.rohm.com ©2010 ROHM Co., Ltd. All rights reserved.
